He seems to be staying out of it for now Jeanne. But he's definitely not being hostile to the other female either. She may be going easy on Aria because she's young and maybe hoping she'll leave on her own. The fact that she's landing on the rooftop of the nest ledge building and acting so confident tells me she isn't going away.
Oh boy. Thanks so much for being there. O'Connor has been displaced before so she may be holding her ground more. Aria would not be that experienced at this.
